Spain – May 30th, 2013

In the Guadalquivir basin, in the southern part of Spain, agriculture is a key economic sector. Due to its privileged agro-climatic conditions, the region grows a wide range of crops, from cereals, oilseeds, sugar-beet and cotton, to varied fruits and horticulture products and olives.

Intensive and extensive productions coexist as well as market-oriented large, medium-size and small farms. However, this highly productive agriculture and its dependant socio-economic structure will be threatened by climate change impacts on water availability and frequency of extreme events such as drought.

The impacts of climate change on the agricultural sector in this region are expected to have large social significance, as this region has the second largest share of agricultural employment in Spain. In consequence, it will be relevant for this region to analyze CC impacts, vulnerability and adaptation strategies across different geographical locations, economic sectors and social groups.

The main issues concerning water management and climate change in this basin are: highly valuable ecosystems threatened by climate change and agricultural activity (Doñana National Park), technical challenges: improving water use technical efficiency (modernization of irrigation techniques), special institutional setting, different from other river basins in Spain, which poses water management under the shared competence of the regional administration and the river basin authority, that can promote mainstreaming of climate change under the water policies (click here for more information).

Sediments from Guadalquivir River and Climate Change Issues, Spain – April 6th, 2013

Spain – April 6th, 2013

The Guadalquivir River is the fifth longest river in the Iberian peninsula and the second longest river with its entire length in Spain. It is 657 kilometers long and drains an area of about 58,000 square kilometers. Here, the river can be seen spilling sediments into the Gulf of Cádiz, northwest of the Strait of Gibraltar. According to scientists, the river shows declines in water quantity and quality due to anthropogenic encroachments and climate change, which is leading to conflicts among stakeholders. The main climate change-related issues are changes in rain patterns, which may cause increased droughts and more torrential rain (click here for more information).

Spain – December 2nd, 2012

Sediments pour from the Guadalquivir River into the Gulf of Cádiz, in the Atlantic Ocean. The Guadalquivir is the fifth longest river in the Iberian peninsula and the second longest river with its entire length in Spain.

The river is 657 kilometers long and drains an area of about 58,000 square kilometers. It begins at Cañada de las Fuentes in the Cazorla mountain range (Jaén), passes through Córdoba and Seville and ends at the fishing village of Bonanza, in Sanlúcar de Barrameda, flowing into the Gulf of Cádiz. The marshy lowlands at the river’s end are known as “Las Marismas”.

This image shows thick patches of clouds hanging over parts of the Iberian Peninsula during the northern hemisphere winter. Visible along the coastline are sediments from rivers such as the Tagus, whose large estuary by Lisbon, Portugal, is best observed near the center left in the full image, and the Guadalquivir, which enters the Gulf of Cádiz by the city of Sanlúcar de Barrameda and the Doñana National Park, in the lower right quadrant. Also visible at the lower right is the Strait of Gibraltar, partially covered by clouds. The strait separates Spain from Morocco, which can be observed upon opening the full image.

This image stretches across Portugal (left) to Spain (center and right). Sediments can be observed along the west coast of Portugal and the shores of the Gulf of Cádiz, the arm of the Atlantic Ocean between Cape St. Vincent (Cabo de São Vicente) in Portugal and Cape Trafalgar (Cabo Trafalgar) at the western end of the Strait of Gibraltar.

Two major rivers, the Guadalquivir and the Guadiana, as well as smaller rivers, like the Odiel, the Tinto, and the Guadalete, reach the ocean here. The Strait of Gibraltar can be seen at the lower right, with part of Morocco partially visible by the clouds at the bottom edge.
